DOCUMENT-FILE.-

SPECIFICATION forming part of Lease Patent No. 646,834, dated April 3,1900.

Application filed January 13, 1900. Serial No. 1,316. (No model.)

To aZZ whom it may concern.-

Be it known that I, HORTENSE T. Iona STROM, a citizen of the UnitedStates, and a resident of New York, in the county of New York and Stateof New York, have invented certain new and useful Improvements in Doc'ument-Files, of which the followingis a specification.

My invention relates to certain improvements in document-files; and theinvention consists in the construction, arrangement, and combination ofparts, all as hereinafter described and claimed. I

In the accompanying drawings, to which reference is made and which forma part of this specification, Figure 1 is a plan view of the front ortop of mynew and improved document-file. Fig. 2 isa like view of theback of the file. Figs. 3, 4, and 5 are enlarged detailed views showingthe construction of one end of the shaftand of the yoke or key forturning the same.

In the drawings, 2 3 represent, respectively, the front/and back boardsof the file. These may be of any appropriate size and of any suitablestifi material-such, for example, as heavy cardboard. The front board 2is ;formed with a flap 4 at one end, hinged at 5 p to the main body ofthe front, so that by turnin the flap back at an'angle to the front 2the papers confined in the file may be inspected or any one of themremoved without disturbing or disarranging the whole or any "0t er orothers of the papers. The flap 4 is 3 5 adapted to be held in line withthe main body 2 flat, and firmly against the papers in the file byafinger or pivoted button, here shown {as a metal finger 6, pivoted tothe main body 2 by a screw or rivet 7.

Thatm) boards 2 3 are united by tapes 8 8? and 9 9*. Th'e ends of thetapes 8 8 and 9 Pare fastened to the back board 3 by metal clips orloops 10 10 and 12 12, secured to the edges of the back board, the clipsor loops 12 5 12 being offset from the position of the clips or loops l010that is, set the distance of the width of the tape, or thereabout,nearer the top of the file, as shown clearly in Fig. 2. The front board2 is provided at its outer surface with a winding-shaft 13 for the twopairs of tapes. This winding-shaft is pivoted at its ends in bearings 1414, projecting from the surface of the front board, the samebeingformed, preferably, as a part of the metal plates 15 15, firmlysecured by screws or rivets to the main body 2 of the front board of thefile, as shown clearly in Fig. 1. The tapes coming from the clips orloops 10 10 and 12 12 pass through loops 16 16 and 17 17 and arefastened to the winding-shaft 13. The loops 16 16 and 17 17 are fastenedto metal pieces or clips 18 18 and 19 19, secured to the edges of thefront board 2, so that they furnish uniform and smooth surfaces for thetapes to draw over whenever they are wound up by turning the shaft 13.The tapes 8 8 wind over the top or outside of the shaft, while the tapes9 9 wind from beneath, as shown clearly in Fig. 1.

The shaft 13 is provided at one end with a yoke, key, or crank 20, bywhich it may be turned for winding up or unwinding the tapes. This keyis hinged to the shaft, so that it may be turned to the right or leftover the top of the board 2, as shown in Figs. 1 and 4, where it serves,in connection with the said board, as a lock to the shaft 13. When thekey is turned out in line with the shaft 13, as shown in Fig. 3, theshaft is free to turn for unwinding the tapes and may also be turned inthe opposite direction by the key for forcibly winding up the tapes anddrawing the front and back boards together for firmlyconfining paper anddocuments placed between them.

The key 20 is hinged to a collar 21, placed loosely on the end of theshaft 13, and a spring 22, operating between the said collar and thehead 23 of the shaft, constantly forces the collar against a pin 24 inthe shaft. (Shown clearly in Fig. 3.) The face of the collar 21 adjacentto the said pin 24 is formed with four or more recesses 25, adapted toengage with the pin 24 in the manner of a clutch. By this clutchformation the key and shaft may be detached from each other by merelypulling back on the key, so that when the Wings of the key are at rightangles to the file and the tapes are wound up sufficiently tight, if itshould then happen that the key could not then be turned to the positionshown in Fig. 1, by pressing the thumb of one hand on the tapes andpulling back on the key it may be disconnected and turned in eitherdirection independently of the shaft to such position that it maybeshifted over the front board in order that it may lock the shaft andhold the file in the position of firmly holding the papers placed in it.

Having thus described my invention, What I claim as new, and desire tosecure by Letters Patent, is

1. In a document-file, a front board, a Winding-shaft held parallel withthe outersurface of the front board and spaced therefrom by bearingssecured to and projecting from the outer surface of said front boaid, akey for turning said shaft, a back board, two pairs of tapes connectedto said back board and to said shaft, and marginal offset guide-loopsfor said tapes secured to the said front board, substantially asdescribed.

2. In a document-file a Windingshaft journaled in bearings projectingfrom the surface of the front board, in combination with a swing-keysecured to one end of the shaft and adapted to be turned over thesurface of the front board for locking the shaft against rotation,substantially as described.

3. In a document-file the shaft 13 journaled in bearings projecting fromthe surface of the front board 2 in combination with a back board, tapesconnected to said front and back boards and to said shaft and a hingedand longitudinally-slidable Winding-key secured to said shaft,substantially as described.

at. In a docuinent-file a shaft 13 journaled in bearings projecting fromthe surface of the front board 2, a back board, tapes connected to saidfront and back boards and to said shaft a pin 24 in said shaft arecessed slidable collar placed in said shaft, a key 20 pivoted to saidcollar and spring for forcing the said collar against the said pin,substantially as described.
